ApplicationInsights customMetrics数据不适用于WebJob

问题描述

我正在使用.Net中的Azure函数和WebJob，并使用TelemetryClient将日志发送到ApplicationInsights.

I'm using Azure function and WebJob in .Net and sending logs into ApplicationInsights using TelemetryClient.

对于WebJob和Azure函数，我具有几乎相同的日志记录代码.

I have almost same logging code for WebJob and Azure function.

对于azure函数，我可以在Requests，Traces和customMetrics中看到我的数据，但是对于WebJob，customMetrics中没有可用的数据，而仅在Traces和Requests中可用.

For azure function, I can see my data in Requests, Traces and customMetrics but for WebJob no data is available in customMetrics only available in Traces and Requests.

我的EventHub WebJob日志记录代码

My EventHub WebJob logging Code

public Task ProcessEventsAsync(PartitionContext context, IEnumerable<EventData> messages)
    {
        foreach (var eventData in messages)
        {
            Log log = LogManager.GetLogger();
            RequestTelemetry requestTelemetry = new RequestTelemetry { Name = "EventhubWebJob" };
            requestTelemetry.Properties.Add("MessageId", Guid.NewGuid().ToString());
            IOperationHolder<RequestTelemetry> operation = log.TelemetryClient.StartOperation(requestTelemetry);
            operation.Telemetry.Success = true;
            log.Trace($"Message processing start...");
            try
            {
                log.Trace("Message received.");
                Console.WriteLine($"Message received.");
            }
            catch (Exception ex)
            {
                operation.Telemetry.Success = false;
                log.Trace(ex.Message);
                throw;
            }
            finally
            {
                log.Trace($"Message processing completed.");
                log.TelemetryClient.StopOperation(operation);
            }

        }

        return context.CheckpointAsync();
    }

我可以在下面看到与WebJob所需的Function相同的数据.

I can see below data for Function same I need for WebJob.

推荐答案

如果要将ApplicationInsights与WebJob一起使用，则即使当前是beta版，也需要使用Microsoft.Azure.WebJobs.Logging.ApplicationInsights nuget软件包.

If you want to use ApplicationInsights with WebJob, you need use the Microsoft.Azure.WebJobs.Logging.ApplicationInsights nuget package even it's a beta currently.

您总共需要三个软件包:

You need three packages in total:

1. Microsoft.Azure.WebJobs.Logging.ApplicationInsights
2. Microsoft.Extensions.Logging
3. Microsoft.Extensions.Logging.Console

配置JobHostConfiguration

Configure the JobHostConfiguration

string instrumentationKey = Environment.GetEnvironmentVariable("APPINSIGHTS_INSTRUMENTATIONKEY");
if (!string.IsNullOrEmpty(instrumentationKey))
{
      // build up a LoggerFactory with ApplicationInsights and a Console Logger
       config.LoggerFactory = new LoggerFactory().AddApplicationInsights(instrumentationKey, null).AddConsole();
       config.Tracing.ConsoleLevel = TraceLevel.Off;
}

注意:不要忘记在应用程序设置中添加APPINSIGHTS_INSTRUMENTATIONKEY.

Note: Don't forget adding the APPINSIGHTS_INSTRUMENTATIONKEY in your application setting.

关于ILogger过滤，您可以参考 Application Insights Integration Wiki，CategoryLevels允许您为特定类别指定日志级别，以便您可以微调日志记录输出.

About the ILogger filtering, you could refer to the Application Insights Integration wiki, CategoryLevels allows you to specify log levels for specific categories so you can fine-tune the logging output.

您可以添加LogError并添加代码:

And you could add the LogError with code:

public static void ProcessQueueMessage([QueueTrigger("queue")] string message, ILogger logger)
    {
    //you can directly use this line of code.
    logger.LogError(new Exception(),"it is a test error...");
    }
